Gyororo, the tadpole keronian with seven eyes that was the shurara corps spy. He was sent on a mission to spy on the Hinata Household and the Keroro Gunsou platoon.

He was captured by the Keroro platoon shortly after in a soap bubble, that was invented by Kururu, and interrogated for information about the Shurara Corps.
He has a habit of putting "de ansu" after his sentences (like Tamama "desu" and Keroro "de arimasu") He also says his name often.
He also seems to have an arrogant, short-tempered and manipulative personality, just by judging the way he used his partner Nuii.
